HOLDING SHEETS IN .REGSTER ON'TAPE CARRIERS.

Application filed October 2, 1923. Serial No. 656,132.

It has been very diilicult to accurately feed sheets cut from light weight and loosely woven fabric webs. This has been especially true in the case of burlap because of the tendency of the material to wrinkle.

The object of my invention -is to provide means coacting with an endless sheet feeding tape carrier for engaging the advance edge of the sheet as it is cut from the web and to maintain contact with the sheet until it is received by the sheet taking means, thereby ensuring the proper feeding of the sheets in register to the said sheet taking means.

My invention comprises more particularly gravity operated rollers frictionally driven by and coacting with the endless tape carrier to engage and maintain control of the sheet from the time it is cnt from the web until it is taken by the sheet taking means.

A. practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents in side elevation a portion of a web cutting and sheet feeding mechanism with my invention applied thereto.

F ig. 2 represents a detail sectional view on an enlarged scale of the sheet feeding mechanism.

F ig. 3 represents a detail plan view of the same.

The web feeding mechanism is herein shown as including the web feed drum 1 and its coacting feed rolls 2. The mechanism for cut-ting the sheets from the web is shown as comprising the coacting rotary and stationary cutting members 3 and 4. Both the feeding and cutting mechanisms may be driven at the desired speed through suitable intermediate gearing from the main drive shaft 5.

The sheettaking mechanism is herein shown as a rotary cylinder 6 which may be a part of printing or folding mechanism, said cylinder having grippers 7 for taking the leading ends of the sheets as they are fed thereto from the cutting mechanism by the endless sheet carriers 8 and 9. The tapes of the upper tape carrier pass around pulleys 10 at the receiving end of the carrier and around pulleys 11 at the delivery end thereof. The tapes of the lower tape carrier pass around pulleys 12 at the inner end of the carrier and around the roll 13, the pulleys 14 and the roll 15 at the delivery end through the gears 29, 30 from the main drive shaft 5.

A. bar 31 extends horizontally across the machine, which bar is provided with a plurality of arms 32, the free ends of which are provided with rollers 33 which normally rest by gravity upon the tapes 9 where they pass over the roll 13 of the lower endless tape carrier. These rollers 33 are arranged to coact with the lower endless tape carrier to engage the advance end of the sheet just as it is severed from the web and to mamtain control of the sheet until the advance edge of the sheet is grasped by the grippers 7 of the sheet taking cylinder 6. It will thus be seen that the sheet will be fed in register to the sheet taking means.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence, I do not wish to be limited to the particular embodiment herein shown and described, but

lVhat I claim is 1. Sheet taking means, an endless tape to the sheet taking means, a roll over which Contact with the sheet until it is received by the tapes of the roller tane Carrier pass, a the sheet taking means, to ensure the proper transverse support, rock arms carried therefeeding of the sheet in register. 10 Vby and rollers Carried by said rock arms in In testimony, that I claim the foregoing 5 position torestby gravity on the said tapes as my invention, I have signed my naine this where they pass over said roll for engaging 28th day of September A.
